Applications Uniform intensity laser lines
•Machine vision•Industrial inspection
•3D contour mapping
•Positioning & visualization
•Biomedical (e.g. flow cytometry)
•High-end alignment Conventional laser line patterns are often generated by cylindrical optics that produce a
Gaussian line profile with a bright center and fading ends. Lasiris™ patented beam
shaping optics spread the light into an evenly illuminated line, resulting in a crisp, uniform line with sharp ends.

Focusing performance
The following figures show the typical focusing and depth-of-field performance of the
SNF laser line generator. The focus charts indicate the minimum line thickness (at 1/e
2 )achievable for a specific projection distance. The depth-of-field is defined as twice the
distance over which the thickness of the line has increased by a factor of
√
2.
